Here's an excerpt from it:
..."Dadi promises Soumya that she will make Suhhani leave the house, but they both make efforts and pressurize Yuvraaj to tell Suhani about his first love for Soumya, and see whether Suhani would be able to accept this truth and still love him with fair respect. Yuvraaj gets tensed to say his love for Soumya and marriage by Pankaj's blackmail truth to Suhani, as he starts
fearing to lose Suhani. Dadi decides to use this opportunity and fill Suhani's ears with the bitter
truth of Yuvraaj's compromise and unhappiness in marrying her. ..."
